Question

I trying to test the connection with my local sql DB. I have this code:

try{
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
    DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=SocialFamilyTree;user=SOSCOMP");

}catch(Exception e){
    System.out.println("Couldn't get database connection.");
    e.printStackTrace();
}

I tried many users. my windows user is SOSCOMP and doesn’t have a password. I also know that SQL 2008 create users as “sys” “dbo”, I tried these too. I’m always getting:

Couldn't get database connection.
com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'SOSCOMP'.

Any ideas?

If you try to connect with database which is using windows authentication, you can use ‘integratedSecurity’ option in your connection string.

DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=SocialFamilyTree;integratedSecurity=true;");
